Herschel Tracks

Post by Eylrid » October 9th, 2009, 3:52 am

I think the next thing I want to learn about is Herschel Tracks: How they work, how they're used, and what they can do.

Herschel tracks are components built solely out of still-lifes. They are used to direct an object called a Herschel (hence the name).

Here is an example of a circular Herschel loop composed of just one conduit:

Code: Select all

x = 83, y = 83, rule = S23/B3

Why use Herschel tracks? One advantage of Herschel tracks over p30 circuitry is that no synchronisation is required. This can be used to make prime-period oscillators.


Herschel tracks form the basis of many stable reflectors. A basic stable reflector is shown below:

Code: Select all

x = 81, y = 64, rule = B3/S23
33bo$31b3o$5b2o23bo$6bo23b2o$6bobo$7b2o2b2o37bo$11b2o35b3o15bo9bo$47bo

This one was found in 1998 by Stephen Silver, and is the smallest 90° reflector (the only stable reflector record that I don't hold!) :lol:

You should be able to follow its operation quite easily. The incoming glider hits a beehive, which results in the eventual production of a Herschel. Miraculously, the beehive is restored.

However, an extra beehive has been created. The purpose of the remainder of the device is to delete the spurious beehive, thus restoring the reflector to its original state.

It has a recovery time of 497, which makes it the third fastest 90° reflector.

The fastest reflector, with a recovery time of 466, is slightly larger. This one was found by myself, and uses a staged-recovery system:

It has a more complex operational cycle, and I shall not bore you with the details. You can read all about it on pentadecathlon.com.
What do you do with ill crystallographers? Take them to the mono-clinic!

Thank you. Is there a library of Herschel Conduits somewhere?

Good point. Dave Greene and I are making a pattern collection of stable technology, which includes Herschel conduits.


There are 22 elementary Herschel conduits, five of which use boojum reflectors.


Here are the remaining 17: (You will require Golly to view this pattern.)

This one was found in 1998 by Stephen Silver, and is the smallest 90° reflector (the only stable reflector record that I don't hold!) :lol:

You should be able to follow its operation quite easily. The incoming glider hits a beehive, which results in the eventual production of a Herschel. Miraculously, the beehive is restored.

However, an extra beehive has been created. The purpose of the remainder of the device is to delete the spurious beehive, thus restoring the reflector to its original state.

Actually, I hold the record for smallest 90 degree glider reflector.

Thank you. Is there a library of Herschel Conduits somewhere?
Good point. Dave Greene and I are making a pattern collection of stable technology, which includes Herschel conduits.


There are 22 elementary Herschel conduits, five of which use boojum reflectors.


Here are the remaining 17: (You will require Golly to view this pattern.)
